21 4 4. Web Management The POE-GSH2004L-370 can be configured by web based interface, including System Information, Ports Configuration, VLAN setting, Aggregation, QoS setting, PoE, IGMP Snooping, Mirroring, SNMP, Loop Detection, Broadcast Strom, configuration/ backup/recovery, log out, and so on. The device based smart switch supports main stream browsers, such as IE, Firefox and Chrome etc to configure the device function. All functions are illustrated below. 4.1 Setup your computer for Web management The Concept of Subnet Under the TCP/IP environment, network devices must be on the same subnet in order to see each other. This means before you can configure the switch through web browser, you must set your computer to the same subnet as the switch. For two network devices to be on the same subnet, they must have the following 2 criteria: Their IP address must be on the same subnet. For example, if one IP address is The other s IP address must be x (x is any number between 2 and 254) for Class C subnet. To find out the IP address information for your computer. Under WinXP/Vista/Win7/Win8, please open Command Line window and type ipconfig. They must have the same subnet mask. For example, if one machine is The other machine must also set to the same mask. 16

22 Configure your computer s IP Before accessing the switch through web browser, please follow the instruction below to configure your computer s IP to the same subnet as the switch. If your switch s IP has not been changed, it should have the following factory default value: The switch s Default IP IP Address: Subnet Mask: Now if your computer s IP is not in the same subnet as the switch, please follow the steps below to change the computer s IP: STEP 3 STEP 2 STEP 4 Figure 4-1 Manual IP setting STEP 1 17

23 Step 1. Double click on the network connection status icon on the task bar. This should bring up a window showing the status of the current network connection. If there is no network status icon on the task bar, please go to the Start -> Settings -> Network -> Local Connection of the task bar s Start menu. Step 2. Clock on the property icon. Step 3. Double click on the Internet Protocol (TCP/IP) Step 4. Click on Use the following IP address button and enter the computer s address manually. This IP address must be on the same subnet as the switch but different from the switch s IP. Please make sure the IP is not used by other network device. If the switch s IP address is of factory s default value. We recommend enter the following for computer s IP: IP Address: Subnet Mask: Gateway: Click Ok after finish entering the IP. Note1: The POE-GSH2004L-370 has DHCP client ability. This allows DHCP server (or router) to assign IP automatically. However, we do not recommend turning on the DHCP client because the DHCP server assign the IP randomly. The DHCP client should be used only when connecting directly to Cable Modem (for remote management) whose service provider uses DHCP for IP assignment. Now, you will be able to access the switch by typing in the switch s IP address on the web browser. 18

24 4.2 Remote Management In this section, you will learn how to setup your computer and the router for remote web management. Remote management allows MIS to manage a switch from outside of the switch s IP domain or from Internet. Depending on the type of Internet connection you have, there are two ways to setup the switch to be available through Internet. Direct Connection to Internet If you have a fixed IP xdsl account or cable modem account, and there is no router in the network, you can connect your switch directly to Internet via xdsl modem/cable Modem. However, this method is not recommended as the LAN will be directly exposed to the Internet. Fixed IP: If your ISP has assigned you a fixed IP. Please go to the Switch s IP configuration and enter the IP address, Subnet Mask, and Gateway information offered by your ISP. If your ADSL connection is PPPoE or PPTP type, you have to connect through a router for remote management. Cable Modem: If your Cable service provider uses DHCP for IP assignment, please turn on the DHCP function under IP configuration. Make sure there is no DHCP server in the network. Then the Cable provider will assign the switch with a IP and Gateway. Go to the console port management to find out what IP has been assigned to the switch. 19

25 When the configuration is finished, the Remote PC can access the switch by typing the switch s IP address on the web browser. Connect through Broadband Router If you have an IP sharing router in the network, you can open a virtual server on the router to allow the switch to be managed through Internet. This method is more recommended as the broadband router provides natural firewall protector from hackers. In the diagram above, the router has the WAN (given by the ISP) port IP address and LAN port address The switch s IP is Please follow the instruction below to setup the router and switch for remote access: On the Switch On the IP setting, set the gateway to Router s LAN port address Please make sure the subnet mask is the same as the router s. 20

26 On the Router Go to router s Virtual Server setting and open the Web port (TCP Port 80) to the switch s IP address If your router require enter the beginning and ending Port (from PortX to PortX), enter 80 for both. Now the Remote PC will be able to access your switch by entering in the Web browser s address field. 4.3 Get Into the Web management After you have properly configured the computer and switch s IP, you can get into the web management by the following steps: Step 1. Open the Internet Explorer Step 2. Enter the switch s IP address in the Address field and press enter. Step 3. When prompt for and Password, enter the following information: Password: airlive You should see the following welcome screen after the process is completed: 21

27 Menu Bar On the left side, the main menu tree for web is listed in the page.

Default: Disable VLAN Mode Configuration Web Smart Switch supports Port-based VLAN and Tag-based VLAN (802.1q). Its VLAN mode supports 10 active VLANs and the available VLAN ID range is from 1~4094. VLAN configuration is used to divide a LAN into smaller ones. With proper configuration, you can gain not only improved security and increased performance, but also save a lot of VLAN management effort. The VLAN Mode Selection function includes two modes: Port-based, Tag-based. 31

37 VLAN mode: Port-based: Port-based VLAN is defined by port. Any packet coming in or outgoing from any one port of a port-based VLAN will be accepted. No filtering criterion applies in port-based VLAN. The only criterion is the physical port you connect to. For example, for a port-based VLAN named PVLAN-1 contains port members Port 1&2&3&4. If you are on the port 1, you can communicate with port 2&3&4. If you are on the port 5, then you cannot talk to them. Each port-based VLAN you built up must be assigned a group name. This switch can support up to maximal 10 port-based VLAN groups. Tag-based: Tag-based VLAN identifies its member by VID. This is quite different from port-based VLAN. If there are any more rules in ingress filtering list or egress filtering list, the packet will be screened with more filtering criteria to determine if it can be forwarded. The switch supports supplement of 802.1q. For more details, please see the section VLAN in Chapter 3. Each tag-based VLAN you built up must be assigned VLAN name and VLAN ID. Valid VLAN ID is User can create total up to 10 Tag VLAN groups VLAN Group Configuration Tag based VLAN mode The VLAN membership configuration for the selected switch can be monitored and modified here. Up to 4094 VLANs are supported. This page allows for adding and deleting VLANs as well as adding and deleting port members of each VLAN. 32

38 33

39 VID: VLAN identifier. Each tag-based VLAN group has a unique VID. It appears only in tag-based mode. Member: In modify function this is used to enable or disable if a port is a member of the new added VLAN, Enable means it is a member of the VLAN. Just tick the check box ( ) beside the port x to enable it. 34

40 Port: Port number. VLAN aware Enabled: Discard other VLAN group packets, only forward this port joined VLAN group packets. Packet Type: All: Forward all tagged and untagged packets. Tagged Only: Forward tagged packets only and discard untagged packets. Pvid: This PVID range will be Before you set a number x as PVID, you have to create a Tag-based VLAN with VID x. For example, if port x receives an untagged packet, the switch will apply the PVID(assume as VID y) of port x to tag this packet, the packet then will be forwarded as the tagged packet with VID 35

41 Port-based VLAN mode ID (Group ID): When you want to edit a VLAN group, you must select the Group ID field. Then, you will enter Tag Base VLAN Group Setting or Port Base VLAN Group Setting page, which depends on your VLAN mode selection. 36

42 Member: In modify function this is used to enable or disable if a port is a member of the new added VLAN, Enable means it is a member of the VLAN. Just tick the check box ( ) beside the port x to enable it. Add Group: Create a new port-based VLAN or tag-based VLAN, which depends on the VLAN mode you choose in VLAN mode function. Delete Group: Just tick the check box ( group. ) beside the ID, then press the <Delete> button to delete the VLAN Isolation Port Isolation provides for an apparatus and method to isolate ports on layer 2 switches on the same VLAN to restrict traffic flow. The apparatus comprises a switch having said plurality of ports, each port configured as a protected port or a non-protected port. An address table memory stores an address table having a destination address and port number pair. A forwarding map generator generates a forwarding map which is responsive to a destination address of a data packet. The method for isolating ports on a layer 2 switch comprises configuring each of the ports on the layer 2 switch as a protected port or a non-protected port. A destination address on an data packet is matched with a physical address on said layer 2 switch and a forwarding map is generated for the data packet based upon the destination address on the data packet. The data packet is then sent to the plurality of ports pursuant to the forwarding map generated based upon whether the ingress port was configured as a protected or non-protected port. 37

43 This page is used for enabling or disabling port isolation on ports in a Private VLAN.A port member of a VLAN can be isolated to other isolated ports on the same VLAN and Private VLAN. Port Members: A check box is provided for each port of a private VLAN. When checked, port isolation is enabled on that port. When unchecked, port isolation is disabled on that port. By default, port isolation is disabled on all ports PoE In PoE section, users can configure Power over Ethernet is enabled or not for each port. Device Guard function can monitor PoE IP cameras and Access Points activities. When device crash and not responding, it will reboot the device automatically. 38

44 PoE Configuration In PoE Port Management function, user can configure the settings about PoE. The switch complies with IEEE 802.3af/at protocol and be capable of detecting automatically that whether the device linked to the port on the switch is PD (Powered Device) or not. The switch also manage the power supplement based on the Class of the PD, and it will stop supplying the power once the power required by the PD excesses the Class, Short Circuit or over temperature occurs. PoE Enabled: To evoke to enable which port supply the power to the PD. Priority: Three options are offered for the user to choose, including Low, Medium, High and Critical. Default is Low. The switch will stop supplying the power to the port based on the order of the priority Low Medium High Critical in case total power required by all PDs linked to the switch excesses the power limit. As the ports have the same priority, then the switch will cease the power supplement from the port with the highest port id (12 1). Allocation (W): The power is consumed by the port. Detection: 4-Point, Legacy, Both. 39

45 Delay time: The delay time of PoE, 0~300seconds, default is 0. Reset: Reset the PoE Port which is select. 40

46 Device Guard There are two device guard method to guard your PoE devices. One is guard Packet the other is guard IP. When Guard Pkts is enabled, the switch will do the failure action if there is no any incoming packet at each port. When the IP is set in the guard IP, the switch will try to ping the IP, if the IP is not reply, the switch will do the failure action. Guard Pkts To Enable the Guard pkts function. Guard IP address To Enable the Guard IP address function, please key in IP address of the PoE device. The switch will ping the devices, if there is no reply. The switch will do the failure action. Please remember that do not disable the Ping echo function in your PoE devices. Interval time To set the interval time. The switch will ping the IP after Interval time. Retry time To set that how many time that the switch will retry when the Pin is not reply Failure action To set the action when PoE device is detected that it is failure. There are two opinion, nothing and reboot. Reboot To set how many time switch will wait, when reboot is required by device guard. 41

47 4.4.7 Aggregation The Aggregation (Port Trunking) Configuration is used to configure the settings of Link Aggregation. You can bundle ports by same speed, MAC, and full duplex to be a single logical port, thus the logical port can aggregate the bandwidth of these ports. This means you can apply your current Ethernet equipment to build the bandwidth aggregation. For example, if three Fast Ethernet ports are aggregated into a logical port, then this logical port s bandwidth would be as three times high as a single Fast Ethernet ports. 42

48 Normal: Set up the ports that do not join any aggregation trunking group. Group 1~8: Group the ports you choose together. Up to 12 ports can be selected for each group RSTP The switch supports IEEE 802.1D-2004 RSTP protocol, the RSTP protocol can backward compatible to legacy Spanning Tree Protocol (STP) and 802.1w Rapid Spanning Tree Protocol (RSTP). Force version: STP and RSTP. Select the STP version you want to enabled. System Priority: This parameter configures the spanning tree priority globally for this switch. The device with the highest priority becomes the STP root device. However, if all devices have the same priority, the device with the lowest MAC address will then become the root device. Number between in increments of Therefore, there are 16 distinct values. Hello Time: Interval (in seconds) at which the root device transmits a configuration message (BPDU frame). Number between 1-10 (default is 2). Max Age The maximum time (in seconds) a device can wait without receiving a configuration message before attempting to reconfigure. That also means the maximum life time for a BPDU frame. Number between 6-40 (default is 20). Forward Delay: The maximum time (in seconds) the root device will wait before changing states (i.e., discarding to learning to forwarding). Number between 4 30 (default is 15) 43

51 Unregistered IGMP Flooding enabled: Just tick the check box ( ) to enable this function. Default: enable VLAN ID: At the IGMP Enable mode being selected, it will list the VLAN ID number. IGMP Snooping Enabled: After IGMP Enabled function start up then user can tick the check box ( function. ) to enable this Default: enable IGMP Querying Enabled: After IGMP Enabled function start up then user can tick the check box ( function. ) to enable this Default: enable Mirroring Mirror Configuration is provided to monitor the traffic in the network. This switch supports one-port mirror multi-ports. For example, we assume that Port A and Port B are Source Ports, and Port C is Mirror Port respectively, thus, the traffic passing through Port A and Port B will be copied to Port C for monitor purpose. 46

52 Source Port: Set up the port for being monitored. Just tick the check box () beside the port x and valid port is Port 1~24. Mirror Port: Use the drop-down menu to select a mirror port. 47

53 QoS The switch offers powerful QoS function. This function supports VLAN-tagged priority that can make precedence of 8 priorities, and DSCP(Differentiated Services Code Point) on Layer 3 of network framework. While setting QoS function, please select QoS Mode in drop-down menu at first. Then you can use 802.1p Priority and DSCP Priority functions. In this function, you can enable/disable QoS Mode and set Priority Control, such as: 802.1p and DSCP. The switch only supports Strict Priority. High priority queue is always passed first p QoS Mode This function will affect the priority of VLAN tag. Based on priority of VLAN tag, it can arrange 0~7 priorities, priorities can map to 4 queues of the switch (low, normal, medium, high) and possess different bandwidth distribution according to your weight setting. 48

54 Prioritize Traffic: Five Prioritize Traffic values are provided: Custom, All Low Priority, All Normal Priority, All Medium Priority, and All High Priority. The QoS setting would apply to all ports on the switch if one of the following values is selected: All Low Priority, All Normal Priority, All Medium Priority, or All High Priority. Port Number: When Custom is selected for Prioritize Traffic, you may assign specific Port Number for 802.1p Configuration p Configuration: Each Priority can select any of Queue. In Default, Priority 0 is mapping to Queue normal, Priority 1 is mapping to Queue low, Priority 2 is mapping to Queue low, Priority 3 is mapping to Queue normal, Priority 4 is mapping to Queue medium, Priority 5 is mapping to Queue medium, Priority 6 is mapping to Queue high, and Priority 0 is mapping to Queue high. DSCP QoS Mode In the late 1990s, the IETF redefined the meaning of the 8-bit SERVICE TYPE field to accommodate a set of differentiated services (DS). Under the differentiated services interpretation, the first six bits comprise a codepoint, which is sometimes abbreviated DSCP, and the last two bits are left unused. DSCP can form total 64 (0~63) kinds of Traffic Class based on the arrangement of 6-bit field in DSCP of the IP packet. In the switch, user is allowed to set up these 64 kinds of Class that belong to any of queue (low,normal, medium, high). 49

55 Prioritize Traffic: Five Prioritize Traffic values are provided: Custom, All Low Priority, All Normal Priority, All Medium Priority, and All High Priority. The QoS setting would apply to all ports on the switch if one of the following values is selected: All Low Priority, All Normal Priority, All Medium Priority, or All High Priority. Port Number: When Custom is selected for Prioritize Traffic, you may assign specific Port Number for DSCP Configuration. DSCP Configuration: 64 kinds of priority traffic as mentioned above, user can set up any of Queue (low, normal, medium, high). In default, Priority 0~63 are mapping to Queue high. 50

56 Loop Detection The loop detection is used to detect the presence of traffic. When switch receives packet s(looping detection frame) MAC address the same as oneself from port, show Loop detection happens. The port will be locked when it received the looping detection frames. If you want to resume the locked port, please find out the looping path and take off the looping path, then select Unlock port and click on Apply to turn on the locked ports. 51

57 52

58 Port: Local port number State: Show the status on the port. Protocol Enabled: Controls whether Loop Detection is enabled on this switch port. When Port No is chosen and enable port' s Loop detection, the port can detect loop happens and port will be Locked. If Loop did not happen, port maintains Unlocked. Unlock port: When ticking the port, port locked will be opened and turned into unlocked. If not ticking the port, Port maintains locked Broadcast Strom Protection When the broadcast packets received by the switch exceed the threshold configured, the port will be blocked for a period of time which can be set. After a configured time, the switch will detect whether the broadcast packets received on the port still exceed the threshold. If the broadcast traffic is still higher than, the port will be closed for a period of time again. If the broadcast traffic is under the threshold, the port will re-open and forward the packets normally. 53

59 54

60 Mode: Controls whether Broadcast Strom Protection is enabled (as a whole). Packet Per Second: It is a threshold. When the broadcast packet traffic in a second is higher than the threshold configured, the Broadcast Strom Protection enable. Unlock Time: The period (in seconds) for which a port will be kept disabled in the event of a loop is detected (and the port action is to shut down the port). State: Show the status on the port. Protocol Enabled: Controls whether Broadcast Strom Protection is enabled on this switch port. Unlock port: When ticking the port, port locked will be opened and turned into unlocked. If not ticking the port, Port maintains locked. 55

61 SNMP Any Network Management System (NMS) running the Simple Network Management Protocol (SNMP) can manage the Managed devices equipped with SNMP agent, provided that the Management Information Base (MIB) is installed correctly on the managed devices. It is a protocol used to govern the transfer of information between SNMP manager and agent and traverses the Object Identity (OID) of the management Information Base (MIB), described in the form of SMI syntax. SNMP agent is running on the switch to response the request issued by SNMP manager. Basically, it is passive except issuing the trap information. The switch supports a switch to turn on or off the SNMP agent. If you set the field SNMP Enable, SNMP agent will be started up. If the field SNMP is set Disable, SNMP agent will be de-activated, the related Community Name, Trap Host IP Address, Trap and all MIB counters will be ignored. 56

62 This function is used to configure SNMP settings, community name, trap host and public traps as well as the throttle of SNMP. A SNMP manager must pass the authentication by identifying both community names, then it can access the MIB information of the target device. So, both parties must have the same community name. Once completing the setting, click <Apply> button, the setting takes effect. SNMP enable: The term SNMP enable here is used for the activation or de-activation of SNMP. Default is Disable. Get/Set/Trap Community: Community name is used as password for authenticating if the requesting network management unit belongs to the same community group. If they both don t have the same community name, they don t belong to the same group. Hence, the requesting network management unit cannot access the device with different community name via SNMP protocol; If they both have the same community name, they can talk each other. Community name is user-definable with a maximum length of 15 characters and is case sensitive. There is not allowed to put any blank in the community name string. Any printable character is allowable. The community name for each function works independently. Each function has its own community name. Say, the community name for Read only works for Read function and can t be applied to other function such as Write and Trap. Default SNMP function: Disable Default community name for Get: public Default community name for Set: private 57

63 Default community name for Trap: public System Event: The System Event trap enable here is used for the Cold Boot or Warm Boot of system Event. Default is Disable. TP and Fiber Port Event: The TP and Fiber Port Event trap enable here is used for the Link Up or Link Down of system Event. Default is Disable. 4.5 Monitoring Monitoring includes the following functions: Statistics Overview Detailed Statistics IGMP Status PoE Status Ping Statistics Overview The section describes to the Port statistics information and provides overview of general traffic statistics for all switch ports. 58

71 4.5.3 RSTP Status RSTP VLAN Bridge Overview Bridge Id: Show this switch s current bridge priority setting and bridge ID which stands for the MAC address of this switch. Bridge Priority: This parameter configures the spanning tree priority globally for this bridge. The device with the highest priority becomes the STP root device. However, if all devices have the same priority, the device with the lowest MAC address will then become the root device. Number between in increments of Therefore, there are 16 distinct values. 66

72 Root ID: Show root bridge ID of this network segment. If this switch is a root bridge, the This switch is Root will show this switch s bridge ID. Root Priority: This parameter configures the spanning tree priority globally for this Root. The device with the highest priority becomes the STP root device. However, if all devices have the same priority, the device with the lowest MAC address will then become the root device. Number between in increments of Therefore, there are 16 distinct values. Root Port: A forwarding port that is the closest to the root bridge in terms of path cost Hello Time: Interval (in seconds) at which the root device transmits a configuration message (BPDU frame). Number between 1-10 (default is 2). Max Age: Show the root bridge s current max age time. Forward Delay: Show the root bridge s forward delay time. 67

73 Topology: Show the root bridge s spanning tree topology. RSTP Port Status Path Cost: It is the contribution value of the path through this port to Root Bridge. STP algorithm determines a best path to Root Bridge by calculating the sum of path cost contributed by all ports on this path. A port with a smaller path cost value would become the Root Port more possibly. Edge Port: If user selects Yes, this port will be an edge port. An Edge Port is a port connected to a device that knows nothing about STP or RSTP. Usually, the connected device is an end station. Edge Ports will immediately transit to forwarding state and skip the listening and learning state because the edge ports cannot create bridging loops in the network. This will expedite the convergence. When the link on the edge port toggles, the STP topology keeps unchanged. Unlike the designate port or root port though, an edge port will transit to a normal spanning-tree port immediately if it receives a BPDU. P2P Port: We say a port is a point-to-point link, from RSTP s view, if it is in full-duplex mode but is shared link if it is in half-duplex mode. RSTP fast convergence can only happen on point-to-point links and on edge ports. This can expedite the convergence because this will have the port fast transited to forwarding state. There are three parameters, Auto, True and False, used to configure the type of the point-to-point link. If configure this parameter to be Auto, it means RSTP will use the duplex mode resulted from the auto-negotiation. In today s switched networks, most links are running in full-duplex mode. For sure, the result may be half-duplex, in this case, the port will not fast transit to Forwarding state. If it is set as True, the port is treated as point-to-point link by RSTP and unconditionally transited to Forwarding state. If it is set as False, fast transition to Forwarding state will not happen on this port. Default: Auto 68

74 Protocol: Show the root bridge s spanning tree topology Port State: Show the current port state IGMP Status Display IGMP status. In Fig. 4-21, the window shows VLAN ID for each multicast group. VLAN Id: Show VLAN Id for each multicast group. Querier: Show the group membership queries status. Queries transmitted: To count the group membership queries transmitted. 69

75 Queries received: To count the group membership queries received.
